Abstract: A substrate treatment apparatus includes: a plurality of solution treatment modules stacked at multiple stages, each configured to perform a treatment using a treatment solution on a substrate; and a solution supply unit configured to supply the treatment solution to the plurality of solution treatment modules, wherein: the solution supply unit includes supply pipelines provided with a solution feeder corresponding to the solution treatment modules; and the solution feeder includes a pump configured to pressure-feed the treatment solution to the corresponding solution treatment module and a filter configured to filtrate the treatment solution, and is arranged adjacent to the corresponding solution treatment module in a horizontal direction.

Abstract: Disclosed is a circuit in which for conducting the scan path test, test clock terminals are provided in a number smaller than that of user clock domains, and a test clock control circuits on respective test clock lines to control whether the pulses of the test clock are propagated or blocked.

Abstract: A semiconductor integrated circuit comprises a first circuit block constituting an input circuit, a second circuit block constituted of a predetermined function block, a third circuit block constituting an output circuit. The first, second and third circuit blocks are cascade-connected in a normal operation. A testing additional circuit for performing a function test for the second circuit block, is provided only at an input side of the second circuit block, and the second circuit block is connected directly to the third circuit block through only interconnections with neither a logic gate nor a multiplexer.

Abstract: A continuous caster mold has a water-cooled inner wall of copper or a copper alloy that is thoroughly covered with pieces of ceramics. A continuous casting process, which uses a mold whose inner wall of copper or a copper alloy is lined with ceramics having resistance to wear, heat and thermal shock, heat conductivity and lubricating property, with the thickness of the ceramics lining varied either stepwise or continuously in the casting direction. The molten metal, which progressively solidifies as its heat is extracted, is withdrawn by taking advantage of the solid lubrication provided by the ceramics lining. The thickness of the lining is varied to prevent the formation of air gaps between the surface of the lining and the solidifying shell and cool the steel being cast according to the desired pattern, and/or to start solidification of the molten metal below the molten metal surface level.
